Y 14 Claims. Y(onlin-.21) r.My invention relates Yto a.l caramel cuttingk inachine and I declare the following to lbe a-full, clear,l concise andeXa-ct'de'scription thereof sufficient to enable anyone skilled inthe art to which .5 it appertains to make and use the same, reference being had tothe ,accompanying drawing in which like referencecharacters referto like parts throughout' the specification. v I

The object of the inventionis to provide a 1Q. candy caramelcutting machine thatwill be free from' the'- objectionable featurenheretoforeexperienced namely, of .the candy ,sticking to the sides of the knife blades and thereby gumming the same to such'anextent as to interfere with l? the normal running of the machine' and also causing frequent-stopping -of the machine for` the purpose of cleaning the knives.

The above objectionable feature 1s overcome in.

the presentinvention by the` use of copper plated steel knives yor by plating vwith any nonferrous metal such as aluminum,brass or the like metals.

The object will be understood by referring to the drawing in which:

Fig. 1 is a perspective view, parts brokenjaway 25. showing v.the candy cutting machine.

Fig. 2 is a detail view showing one of the knives employed.

Fig. 3 is a detail View showing a modification of one of the knives employed.

30 Fig. 4 is a detail enlarged view showing a central vertical section of one of the knife holding members.

Fig. 5 is a central vertical section taken on line 5-5 of Fig. 1, parts being broken away.

35 Fig. 6 is a sectional View taken on the line 5-6 of Fig. 1, parts being broken away.

Referring more particularly to the drawing, the

candy caramel cutting machine embodies the cutting knives I and 2 and the caramel separat- 40 ing knife 3. Each of the knives, I, 2 and 3 is rectangular in shape and has beveled upper and lower edges 4, 4, to fit in a removable manner into corresponding grooves made in the knife clamping member 5 hereinafter described. Furthermore, each of the said knives are of the same thickness from end to end and is brought to a knife cutting edge at 6.

Moreover, each of the knives is made of steel and copper plated. The copper plate has been found to allow the knife to pass through the candy without said candy sticking or in any manner adhering to the sides of the knife, thereby overcoming the objectionable feature herein- 55 above mentioned,

It is essential that a copperplated steelknife be used; VVcopper alone'is too soft'for the purpose.,V

Each of the cutting knives I and 2 is remov-l. ably held-'in cutting. position by an L shaped holding member IIl in `one instance and, I I inthe other. Holding member Il) is formed integral, brazedV or otherwise fastened rto the end of rock arm I5, whereas holding-member I I is formed in;- tegraLbrazed to therupperjsurface of cooperative rockarm I6,` `Holding menriber.` I8-;1is..likewise formed or; mounted `to the end of arm II.v A,

An auxiliary clamping member 5 is used in connection with each of thehoidingmembers flo, II andi' I8. Itis secured to said membersby a screw bolt20 that projects therethrough vr and engages a threaded aperture in the; baseipartZI of each of said holders IU, II and-I8; '.Ihe-uppeiv part of auxiliary clamping member` 5 is provided with a beveled vgroove 25 to conform to 'thel beveled upper-edge of knives I, Z-and 3. `'.l'lzuelower beveled edge 4 of each ofsad knives rests lin corresponding-,beveled groovesuin base partHZI of L shaped members II), Il and Ij8.V Clamping members 5 will holdknives I, 2 and 3 rigidly in removable position,lwhereby tojwithstand :any strain thereon occasioned by cutting the'candy caramel 30 represented by dotted lines in Fig. 1 as it passes along caramel chute 3I.

Caramel chute is channel shaped and ends adjacent the location of cutting knives I and 2, whereby to allow for a Slight lateral swing of the. free ends of cutting knives I and 2 between said end 32 of chute 3I and the contiguous end 33 of auxiliary chute 34.

Auxiliary chute 34 is fastened by bolts 35, 35 to movable knife bar 33. The heads of bolts 35, 35 are countersunk in the surface of chute 34 to effect a smooth upper surface thereof.

The parts of the machine immediately connected with the cutting knives I and 2 and separating knife 3 embody the said movable knife bar 36 which is mounted to slide in guide posts 31, 3l fixed to the stationary part of the machine.

Rock arms I5 and I6 are pivoted at 40 to movable knife bar 36 and move therewith. The upper head of pivot bolt 4i! is countersunk to bar 36. It projects down through a washer 4I and is secured on its lower end by lock nuts 42, 42. Washer 4I is fastened to the under surface of bar 36 and lies between the upper surface of enlarged part 45 of arm I5 and the under surface of bar 33. Bar I3 is also enlarged at 46 and rests beneath enlarged part 45 of arm I5. Washer 4I is fastened to knife bar 36 by countersunk bolts 48. 48.

Caramel chute 3| is held stationary above knife bar 36 by one of the posts 31.

The means for rocking bars I5 and |6 on pivot 40 as a fulcrum embodies a cam 55 having cam grooves 56, 56 in opposite sides of its lateral faces. Cam is mounted to turn with shaft 51 carried in loose bearings formed in upright supports 58, 58 secured at their bases to a stationary part of the machine.-

Rollers 60, 60 engage cam grooves 56, 56 and are supported in each instance on studs 6|, 6| in upright rocker arms 62, 62. The lower ends of rocker arms 62, 62 are swiveled on shaft 63 carried in bearings in supports 58, 58.

Each of the connecting rods 65, 65 is joined at one end by a ball and socket joint 66 to upright rocker arm 62 and at the other by a loose or pivoted joint 61 to the lower end of depending bolt 68, that in each instance is screw mounted to and projects through the rock arms I5 and |6.

`VThe means for moving the cut caramel forwards towards the paper winding wrapping machine, not shown, embodies cam 10 having a cam groove 1| formed in its circumferential or peripheral surface. Cam 10 is mounted to turn with shaft 51.

A roller is mounted on the free end of a straight shaft 13 and fits in cam groove 1 I. 'Ihe opposite end of shaft 13 is rigidly fixed to rock member 15. Rock member 15 is pivoted at 16 to upstanding bracket 11 fixed to a stationary part of the machine.

A second straight shaft is also rigidly fixed to the'upper part of rock member 15 and above the location of the bearing of shaft 13. The free end of shaft 80 has a loose t in the inverted U member 8| formed integral with the lateral edge of knife bar 36.

Straight shaft 13 is located below straight shaft 80, whereby to step up or increase the throw of cam10.

In operation the strip of candy shown by dotted line 30 in Fig. 1 is passed along chute 3| until it reaches knives I and 2 which are actuated inward by cam 55, whereby to cut the strip at proper lengths. Likewise, separating knife 3 is moved inward simultaneously with knives I and 2 to engage the cut previously made in the strip and by moving through said cut sever the cut caramel from those approaching from knives I and 2. This is possible because knife 3 is mounted on the end of arm I6.

While knives I, 2 and 3 are in the cutting position they are moved to the right to push the separated caramels and the one just cut towards the paper wrapping machine, not shown. At the end of this stroke, cam 55actuates knives I, 2 and 3 to open or dotted line position illustrated in Fig. 1 and thereafter cam 10 actuates them back to original position with knives l, 2 and 3 still open. Whereupon, the several operations are repeated to cut, sever and advance another caramel.

The modification illustrated in Fig. 3 shows a knife having a flat surface to cooperate with knife such as 2 or 3 having a sharp edge 6. In this instance the sharp edge 6 will abut against the fiat edge of knife 9| for cutting purposes.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:

1. In a caramel cutting machine, knives for cutting candy caramels and a copper plated coating applied to said knives, whereby to prevent the candy sticking thereto.

2. In a caramel cutting machine, knives for cutting the strip of candy and said knives being plated with a nonferrous metal to prevent the candy from sticking thereto.

3. In a caramel cutting machine, knives having beveled edges whereby to aid in retaining the same in position and said knives being copperi plated, whereby to vprevent the caramel sticking.

thereto.

4. In a caramel cutting machine, rectangular shaped knives, said knives having beveled edges whereby to aid in kholding them in assembled posi.

tion and a copper plating covering the surface of said knives, whereby to prevent the caramel adhering thereto.
